GAS BURNER.

Application led November 24, 1924. Serial No. 751,806.

4 To aZZ whom 7'1 may concern.'

Bc it known that we,.JAY M; AXTELL and Fimo G. VON HOFEN, citizens ofthe United States, residing at Fort VVOrth, in the county of Tarrant andState of Texas,have in-` .gas so that uniform pressure is maintained forall the jets. The object is to providegas burners for general heatingpurposes and particularly to burners in u'hichfthe circulation of thevgas will exert substantially the same pressure at all points in theburners so that the burners will furnish heat of substantiallyfthe sametemperature throughout the heated zone. Other objects and advantageswill be fully explained inthefollowing description and the inventionwill be more particularly pointed out in the claims.

Reference is/had to the laccompanying drawings which form a part vofthis application. v v

Fig. 1 is a lan view of the improved burner. Fig. 2 1s a horizontalsection of the same.' Fig. 3 is 'a plan view of abut-ner which ,is aslight 'variatibn of the burner previously shown. l Similar charactersof reference are used to indicate the same parts throughout the severalviews.l

-The burner is preferably made of a single casting having a generalquadrangular shape with a central membercommunicat- ,ing with the endmembers. The receiving end 1 is provided with alboss 2 into which isscrewed anozzle 3 forl suppl ing gas to the burner. is threadedinteriorly `to receive the end of a suppl pipe 5. The end member 1 hasan interior y projecting boss 6 which forms a socket for the inner endof the nozzle 3 and also as a gas directing'means for the returncurrents of gas. Gas is fed through the nozzle into a central member 7whlch is connected with'and communicates with the end vmember 8. The endmember'8 is connected with and communicates with the side members 9 and10 which also communicate with the end member v1. The members 1, 7, 8,9. and 10 all have passage for zas and may be The outer end 4 o thenozzle tubular in form. Openings 11 are made at the corners of theburner in line with the members 9 and 10 for` convenience in lthemanufacture ofthe burners. These openings are to be closed with am7suitable plugs. The burner is provided with any' convenient or requirednumber of burner nozzles 12 to be distributed according to the type ofheater in which the burner is to be used.

In operation the gas enters the central member 7 and takes the directionof the arrow heads. At the closed end 8, the gas is divided fordistribution and circulation through the lateral members 9 and 10. The

end member 8 is provided with Aan inwardly A projecting divider 13 Yfordividing the gas.

The gas, in passing through 'the conducting members 7, 8, 9. and 10 isfed to the nozzles 12. When the gas reaches the member 1 on the returntrip, it is deflected bythe defiector 6 into the member The gas inpassing through the nozzle 3 tendsvto create a suction vwhich draws thegas from the members 9 and 10 and(drives the same through the member Inthis lnanner, the gas pressure is maintained substantially uniforntxinall -the members 1,- 7,'8, 9, and '10,

In the form of burner shown in Fig. 3, the lateral lmembers 14 and 15are substantially circular with no end members. At the sidediametrically opposite the supply nozzle 4, a divider 16 serves todirect the passing gas into the members 14 and 15. 4The members l14 and15 have inwardly projecting circulating vmembers 17 which are providedwith battles 18. The gas will be compelled to take the direction of thearrow heads. The circulation of gas in this form of burner is similarto' the circulation of the gas in the form shown in Figs. 1 and 2.

What we claim, is,-

1. A gas burnercomprising distributing p members consistin` of a centralreceivin member, end mem ers connected therewit and communicatinvtherewith and said end members having dividers, and lateral-memberscommunicating with said end members, and a receiving nozzle fordirecting gas through said central member, said distributing membershaving burner nozzles.

2. A gas burner com rising circulatinV members provided with urnernozzles and consisting of a central receiving4 member, a receiving endmember providedv with an 1nwardly projecting divider for directing gasto said central member, an end member con- ,los

- nected with said central memberat the discharge end and provided withan inwardly gas into said central member.

3. A gas burner com rlsing circulating members provided with burnernozzles and consisting of a central circulating member having areceiving end and a discharge end, lateral circulating members onopposite sides of said central member and 'connected with andcommunicating with both ends of said central member, a-divider delectorat the discharge end of said central member for directing gas into saidlateral members, and a nozzle for supplying gas from'the supply sourceto said central member and for aiding in directing gas from saidlateral, members into the receiving end of said central member.

In testimony whereof, We set 'our hands, this 19th day of November,1924.
